Answer 2

To simplify the given expressions, let's solve each of them step by step:

1. 3(x - 7) + 5x

First, distribute the 3 to the terms inside the parentheses:

3 * x = 3x 3 * (-7) = -21

The expression becomes:

3x - 21 + 5x

Next, combine like terms:

3x + 5x = 8x

The simplified expression is:

8x - 21

2. 5(4 - 3x) + 8x

Again, distribute the 5 to the terms inside the parentheses:

5 * 4 = 20 5 * (-3x) = -15x

The expression becomes:

20 - 15x + 8x

Next, combine like terms:

-15x + 8x = -7x

The simplified expression is:

20 - 7x

So, the simplified forms of the given expressions are:

1. 8x - 21
2. 20 - 7x
